the reason im sharing these glitches it because quite a few people dont now about them so im not the founder of the glitches i have shared, i am just helping

steps

1. go to criminal minds
2. set the race settings to ( THIS IS THE IMPORTANT BIT )
race type = standered
no of laps = 2
class = super
time of day = noon
weather = doesnt matter
traffic = on
wanted levels = on
custom vehicles = on
catchup = off
radio - your choice

now before you invite anybody you need to make sure you change this setting
SPLIT TIMES = PERSONAL+++++++++++++++++++++++++++++++++++++++++

that bit is very importent , you can only change that if you are in the race lobby on your own

3. press confirm settings
4. invite you mates in and race
5. it doesnt matter who wins or losses you should all get around 7k in total
6. you can go as fast as you want around the track , crossing the finish line slowly does not improve how much rep you get

tips
1. if you are losing then keep going in and out of slipstream / slipstream boost
2. get everyone to like the race then press replay and you can keep replaying it
